Optional bounding-box computation: return false to default to a standard bbox computation loop. Return true if the BBOX was already computed by the class and returned in "bb" so it can be avoided to redo it again. Look at bb.size() to find out the expected dimensionality (e.g. 2 or 3 for point clouds)
